Ben Greenfield is one of the country’s most well-known personal trainers, not only due to his numerous certifications and popularity, but also due to his passion for biohacking - a concept of increasing our body’s efficiency by means of taking supplements, adjusting our diet and exercise, or making use of technology without losing focus on health and longevity.

Today, Ben tells us his thoughts on testosterone decline, the tips and tools he uses to keep his testosterone in check without injections, as well as the different ways he maintains his body, especially when it comes to getting quality sleep.


“You want to make sure everything's unplugged. Make sure your eyes can't see anything and make sure your skin can't see anything.” Ben Greenfield

 In this episode, you’ll learn:

  • Once you reach 30 years of age, testosterone is said to decline at a rate of 1% a year.
  • Aside from proper nutrition, one of the most recent methods you can do to biohack your testosterone is by shining low-level laser light or infrared light on your testicles.
  • Ben says it’s better to eat buffalo or bison meat than tuna or nuts for testosterone production.
  • An herb called Cistanche acts like Viagra. It results in an increase in blood flow and libido.
  • Not wearing tight underwear (or no underwear at all) might boost testosterone due to a cooler temperature as a result of going commando.
  • PEMF or Pulsed electromagnetic field therapy is able to negate the deleterious effects of waves from continuous smartphone use.
  • Chronic cardio or excess workouts may crash testosterone. Some exercises done in moderation are capable of increasing testosterone include sprinting, weight lifting particularly those largely involving legs, and HIIT or high intensity interval training.
  • For cardio, try to limit endurance training such as marathon running to once a week to preserve testosterone.
  • Sleep is also an important factor when it comes to testosterone production. Ben recommends a lot of tools you can use to get quality sleep. Some of them include essential oil diffusers, a full/wrap-around face mask, and even a few sleep supplements.


Key Takeaways:

  • To get the best quality of sleep, you must have what we call sleep hygiene. The room must be dark, quiet, cold, and definitely not stressful.
